Well, I'd say you're wrong with your statement about needing a "genius" to design a drogue/nozzle system. Most of the engineers I worked with on 75% of the design were nothing spectacular - however, when it came to integration to the airframe and its' impact on aero performance, there you are wrong. Those aero guys who designed the GVT to validate the design are some of the smartest guys I've ever seen; to be without them would be to build a kluged system.
They must not have used the geniuses when they designed the wing refueling pods for the 135. The receiver is flying in the edge of the wingtip vortices, but that isn't critical because once your in the basket you don't have to be that steady. If you screw up the placement of a boom it would be a totally different situation.
